There's still no word on who caused the fire, or how it was caused, but authorities have been investigating and seeking information from the public about the origin of the fire, or even anyone who looked suspicious around Slide Rock on May 20.

Between yesterday and today, the size of the fire increased to a little more than 21,000 acres, but the containment is at 55 percent, up from yesterday's level of 45 percent.

Firefighters have been able to keep the fire contained west of State Route 89A, and although that highway has been closed essentially since the fire started, it's now been reopened for local residents only. According to information released by the Forest Service, only "verified residents" will be allowed past the roadblock.
